Introduction
ATC GT-30 Agricultural Crawler Tractor
The ATC GT-30 is a crawler tractor produced between 1951 and 1954 in Churubusco, Indiana, USA. Designed for agricultural operations, this model is recognized for its compact design and mechanical simplicity, providing traction suitable for various field tasks.
Engine and Performance
The GT-30 is equipped with a Continental F140 gasoline engine. This 4-cylinder, liquid-cooled power plant features a displacement of 139.6 cubic inches (2.3 L) and a compression ratio of 6.5:1. The engine is rated at 1850 RPM and delivers approximately 33 horsepower. It utilizes an oil bath air cleaner for filtration and relies on a manual starter system operating on a 6-volt electrical circuit.
Transmission and Drivetrain
The tractor utilizes an unsynchronized gear transmission providing 3 forward speeds and 1 reverse speed. Power is transferred through a dry disc clutch. The drivetrain is configured as a crawler type, featuring 10-inch tracks that provide stability and grip on uneven ground. The transmission system has an oil capacity of 8 quarts (7.6 L).
Controls and Hydraulics
Steering is achieved through a manual system, paired with mechanical contracting band brakes to manage the crawler's movement. The tractor includes a rear power take-off (PTO) that operates at 540 RPM when the engine is running at 1622 RPM. The operator station is of the open type, focusing on functional accessibility.
Conclusion
With a weight ranging between 3400 and 4471 pounds, the ATC GT-30 is a specialized machine intended for agricultural applications where traction is prioritized over high-speed transport. Its robust mechanical construction makes it a notable example of 1950s American tractor engineering.
